Stuttgart 2028 visitors travel to Germany on Schengen rules: short-stay business travellers from many non-EU countries need a Schengen C visa for stays of up to 90 days within a 180-day period, applied for before departure. EU/EEA and visa-exempt nationals can attend without a visa but must carry a valid passport and proof of the trade fair purpose. Confirm your nationality-specific requirement with the German mission in your country of residence.
The Federal Foreign Office page is the authoritative reference for German visa categories and document lists; commercial portals such as how-to-germany.com and germany-visa.org also describe the business visa route but are not official. Apply through the German embassy or consulate responsible for your place of residence and allow extra time for appointments in peak spring travel season.
